Smart app for Martin guitar owners – Martin Guitar Tuner Review

Thrilled to find this app, as we're a family of Martin owners. Nice looking design and quick to navigate. The tuner is decent. I especially like the Strings part where it shows how to properly change the strings and reviews the various Martin strings available. Only thing missing is maybe chord charts/examples - but I'd be willing to pay for an enhanced version.
